Electronic paper 100 according to the present invention includes a first substrate 10 with first electrodes 14, a second substrate 20 with second electrodes 24, and a powder sheet structure 50 arranged between the first substrate 10 and the second substrate 20. The powder sheet structure 50 includes a bottom substrate 52 and a top substrate 54 opposed to each other, a dividing wall layer 56 including dividing walls 55 arranged between the bottom substrate 52 and the top substrate 54, and powder particles 30 enclosed between the adjacent dividing walls 55 in the dividing wall layer 56. The powder sheet structure is arranged so that the bottom substrate is opposed to the first electrodes of the first substrate, and that the top substrate is opposed to the second electrodes of the second substrate.
